CHECK-ROWER ATTACHMENT FOR CORNPLANTERS.

SPECIFICATION forming part of Letters Patent No. 295,375, dated March 1'?, 1884.

Application filed December 2li, 18H3.

fo all' whom it may concern.-

Be it known that I, HENRY FARMER. a resident of Richmond, in the county of 1Wayne and State of Indiana., have invented certain new and useful Improvements in Check-Bower Attachments for Corn-Planters, of which the following is a. specication.

` My invention relates to that class of checkrowers which employ a knotted cord running parallel with the plane or path of the travel of the planter.

The object of my invention is to provide a simple, cheap, and efficient device to be driven by a straight knotted .cord or wire engaging with the forked lever at either end of the machine, all of which will be fully set forth in the description of the accompanying drawings, in which- Figure I represents a plan view of my iniprovement attached to the check rower or planter-frame. Fig. 2 is a similar plan View, showingl the actuatingpawl in its forward po sition. Fig. 3 is a section on line o: w, Fig. 1. Fig. i is an end sectional elevation of the forked lever. Fig. 5 is a perspective view of Fig'. 6 is an end elevation of the crank-lever. Fig. 7 is a modification of the pawl and drivingcrank.

A represents arms, upon which the oscillating shaft is journaled; A', a transverse oonnecting-bar forming part of the frame.

B represents the oscillating shaft, jonrnaled upon the arms AA. d

C C represent forked levers loosely swiveled upon the oscillating shaft B. Myimprovement is designed to be operated by either one of these forked levers G G. In order that one lever may rest and he idle when the other is engaged by the cord, I provide the following devices:

D represents asegmental disk,\vhich is provided with a segmental hub, d, by which the disk is rigidly secured to the oscillating shaft B.

E represents alug projecting upon the front edge or the disk D. The forks or levers O C are shown as constructed of two pieces of metal, c, between the lower ends of which the disk D projects. Fig. 4. shows the position of the forked lever C when not in use. As' the knot-ted cord engages with the fork and carries it forward, it engages with the lug E and (No model.)

oscillates and moves the shaft B. When forked lever C is released from Contact with the knotted cord', the shaft is retracted by a spring, and the lug E strikes against the lever C, and oarries it back into its normal position. The opposite fork, being hung loosely on the shaft, will not move. In order to reciprocate the seedarm or shaker-bar of the dropping device, I provide the following mechanism:

F represents a crank or arm rigidly secured to the shaft B.

G represents an actuating-pand. g represents the shank, which is loosely pivoted between the forks of the crank-arm F. This actuating-pawl is preferably made ofthe shape herein shown. It is provided with two lugs, g', upon the under side of each of the arms. In the rear of these lugs the metal is cutaway so as to form an incline, to allow them to be raised out of engagement.

H represents a double-acting crank. journaled upon a short stud or shaft, k..

I I represent hooks or notches formed at the outer edge of each ofthe crankarins.

.I represents a lug formed upon the rear end of the pitnia-n-arm K. It projects upwardly so as to 'engage alternately with the opposite edge of the arms of pawl G, to shift it from side to side, to alternately engage with hooks I I of the crank.

L represent-s the pitnian, which is pivoted to a crank-pin on the under side of the crankarm K.

lil represents the shaker-rod, to which the pitmnn L is pivoted to operate the seed-drop ing' mechanism.

N represents a coil-spring wound around the shaft B, one end of which is secured to the lug n, the forward arm of said spring being connect-ed to the frame A.

I do not desire to limit myself to the precise location of the retractile spring7 which carries the arm B backward in its oscillating movement, as various modifications thereof may be made.

rlhe operation of my device is as follows: When the knot-s of the wire or cord stretched across the field come in Contact with the fork of arm C or of arin G, as the case may be, it carries it forward in the usual manner, oseillating the shaft B, and moving the driving pawl G forward. One of the lugs g upon the It is IOC under face of the pawl G engages with, say, the notch I of the crank-arm H, which carries the same forward, the opposite arm, I, being carried backward until it occupies the position shown in Fig. 2. lIhe crank-arm J is moved laterally, as there shown, and the pitman L, being pivoted to the arm K, is reciprocated, one stroke operating the shaker-arm and dropping a charge of seed. Vhen the forked arm C is released fromA engagement with the knotted cord, the shaft B is retracted by the spring N, and the pawl G is also 'retracted and broughtinto the position as shown in Fig. 1. The incline upon the under side of the arm G of pawl H rests upon the crankarm,.and, as it movesbackward, is lifted by theincline out of engagement with the notch I. The lug J on the arm K strikes the outer edge of arm G, which moves the pawl laterally to the left, during this back ward movement, Vuntil it drops, so as to engage the opposite lug y on the under side of the opposite arm of pawl G into engagement with the hook I on the opposite end of the double-crank arm H. A second forward or oscillating movement of the shaft B propels the pawl G forward in the same manner, and it being engaged with the opposite end of the crank H, the movement of the pitman L is made in the reverse direction, thereby moving or reciprocating the shaker -rod in the opposite direction, and planting a second charge of seed. It will be thus seen that the lugs g g of pawl G engage laterally with the hooks on ends of crankarms I I', and plant a charge of seed with each alternate movement of the crank H and pitman L.

I do not desire to limit my invention to the use ot' the crank F on the oscillating shaft B, nor 4to the vertical forked levers C G, as these vertical arms G may be made to work in a horizontal plane. Fig. 7 shows this form of horizontallymoving forked lever, C representing the forked lever, O representing a bellcrank arm secured to the shank of fork C. l? representsa pivot, on which the bell-crank C O is'journaled. Q represents a pitman or arm secured to the pawl G, so as to reciprocate it directly without the use of a transverse oscillating shaft, BQ The bell-crank C O is a substitute for the oscillating shaft B. A similar connection may be made on the opposite end of the pawl G for the other fork-arm, G, and the crank arm H turned a quarter round, and the pitman-crank attached to one of arms I I, so as to reciprocatein the same plane as pawl G.

Various other modications may be made in the details of construction without materially departing` from the feature of my invention.

The crank H is shown as journaled on a stud out of position.

Vsecured to two guards, B and S, which aresemicircular in form, and serve to support the crank H and prevent the pawl G from being thrown Other means, however, may be employed to mount the crank and support and hold these parts in position.

By constructing the driving-pawl and double-acting crank-arm with the lugs and inclines placed upon them, as here shown and described, I avoid iitting the parts, as the lugs and notches will readily act in the engagement without any material lost motion.

The devices are not only cheaply constructed, but are very durable and positive in their connection.

I have shown the double-acting crank-arm H operated by the lugs and pawl as the preferred form of device. It is obvious, however, that a disk may be employed in lieu of the crank-arm H, having segmental teeth upon its edge, engaging with the pinion and crank-pin to oscillate the pinion and move the crank and pitman L by each alternate reciprocation of the pawl in place of the crank-arm J and crankpin, as here shown; butthe device constructed as I have shown is simpler and cheaper, and is of the preferred form.

I claim- 1. A check-rower device composed, essentially, of the double-acting pawl G, in combination with the double-acting crank H, or its equivalent, adapted to be intermittent-l y reciprocated, substantially as herein set forth.

` 2. Ina check-rowerdevice, the combination, with the pitman L, of the shaker-bar, the double-acting crank H, adapted to be alternately oscillated by a double-acting pawl for reciprocating the pitman, substantially as herein set forth.

3. In a check-rower device, the double-acting crank H, provided with the lug J, in combination with the doubleacting pawl G, where by the pawl is brought into alternate engagement with the opposite crank-hooks, I I, substantiall y as herein set forth.

4. The combination ofthe pitman L, the oscillating crank H, the double-acting pawls G, reciprocated by means of theoscillating shaft B, substantially as'herein set forth.

5. In a check-rower device, the combination, with the oscillating shaft B, of the fork C, loosely journaled thereon, with the lug E, secured to said shaft, whereby it is oscillated by engagement of one of the forked levers with said lug, substantially as herein set forth.

In testimony whereof I have hereunto set my hand.

HENRY FARMER.
